Resumen:	This study aims to investigate the relationships between personality traits of impulsivity, using the UPPS-P Impulsive Behaviour Scales shortened version, and prefrontal cortex (PFC) activity during the IOWA Gambling Task (IGT) in young adult women. The study included a sample of 83 young, healthy females (19. 8 ± 1. 4 years), who voluntarily took part in the study. Repeated measures analysis during the IGT revealed a significant increase in HbO (all p <. 001; η >. 31) and a decrease in Hbr (all p <. 003; η >. 08) in all prefrontal quadrants. This increase in oxygenation occurs primarily during the choice period under ambiguity (r =. 23; p =. 039). Additionally, there was a significant linear decrease in selecting the decks associated with a high frequency of losses (p <. 001), while the favorable deck with low losses showed a linear increase (F = 12. 96; p <. 001). Notably, discrepancies were found between UPPS-P and IGT impulsivity ratings. The Lack of Perseverance and Lack of Premeditation scales from the UPPS-P were identified as significant predictors of HbO levels, mainly in the two quadrants of the left hemisphere's, lateral (adjusted R =. 23; p <. 001; f =. 34) and rostral (adjusted R =. 13; p <. 002; f =. 17). These findings suggest that young adult women predominantly adopt a punishmentavoidance strategy during IGT, exhibiting increased activation in the left hemisphere, especially during the task's initial phase characterized by ambiguity.
